In 1607, when England sent its Pilgrims, they're not sending their best. They're sent Pilgrims that have lots of problems, and they brought those problems with them. They're bringing drugs. They're bringing crime. They're rapists. And some Pilgrims, I assume, are good people.
Um, what? Is this a Trump quote? The fractured grammar and tense errors "when England sent" (past tense) "they're not sending their best" (present tense) etc, etc, sound very much like Trump's mumble-stumbles, but I have no idea what's actually going on.
